To allwlw'm 'it may concern:

. Beit known that I, WnLLiNGToN W. Dan-l 4LING, -"residing at Deltain the county of Delta and StateA of Colorado, have invented a new and Improved Resilient Wheel, of

which the following is a specification.

rThis invention, which generally relates to wheels -for motor.vehicles and the like,

more particularly has reference to that class of tubeless tire wheels in which spring devices are utilized for relieving the axle and running gear from shocks or jars.

Resilient wheels have heretofore l been4 vtion of my improved lvehicle wheel. Fig. 2,

provided whose rims have movement" relatively to and transversely of the axle, and in which radially disposed cushioning members between the rim and the axle are em` ployed foitaking up and distributing the Jars and shocks, but such types of Wheels, so far as I know, do not meet all the desired requirements for a safe and eiiicient wheel, of the type stated,and in which the use of a cushion tire is not required.

My invention primarily seeks to provide a wheel of the general type mentioned in which the resilient, or elastic portion, is

'so arranged, -with respect to'the 'ax e and the wheel frame, that a substantially solid metal rim is utilized and the parts so designed and coperat-ively arranged whereby to reduce thedanger of dust or dirt entering between the wheel sections andthe c'ush;

ioning devices to the 'minimum and where. .by the several parts can be readily separated and removed when necessary to get at any of the' interiorworking parts of the wheel,

Another object of my invention is to provide an improved arrangement of parts.

whereby the hub and axle remain substantially stationary, that is,'-lhave no vertical or lateral "sagging movement, and whereby- 'the desired flexibility necessary to act as a complete shock absorber is obtained.

With other objects in view that will here.- inafter appear, my inventionl comprises an improved construction of a two-part metallic wheel body whose tread or rim fportion isa solid tubular member and which is tween the tubular portion of thewvheel and the hub, for yieldingly. sustaining the wheel vWit-l1'respect to the axle and hub and which provision is also made for permitting a substantially universal motion of the wheel body on the axle and hub when the'said wheel passes Vover obstructions or rough places. y E. In its more subordinate nature, my invention consists in certain details of construction and novel 'arrangement of parts, all of which will be hereinafter fully` explained,

'specifically' pointed out in'the appended claims, and illustrated .inthe accompanying drawings, 1n which Figure l, 1s a side elevatlon, partly 1n seois a vertical cross section thereof taken on the line 2-2 on Fig. 1. Fig. 3, is a perspective view of the outer shell member of the wheel. Fig. 4;, is a similar view of the inner shell member hereinafter described in' dee tail. Fig. 5,v is a perspective viewfof the inner or hub bearing ring and spring rest. F ig. 6, is a detail section of a modified construction of the hub and they inner or hub bearing ring and, Fig. 7, is a perspective view of the modified form of hub.

. In the practical application of my invention, the wheel is made up in different diameters to suit the standard sizes for automobiles, railroad or street cars, or other vehicle wheels and the said wheel comprises a body formed of two like' hal-f sections in the nature of steel platesv that are pressed or otherwise formed, each having a flat port-ion 1 and a semi-circular tubular shaped rim .10, the two sections. being opposites so that when' the said two sections are joined and bolted u their rim portions produce a substantial y solid tubularrim, the art-s being also so formed that the entire 'internal mechanism of the wheel is entirely ineased or -closed in to prevent'the entrance of dirt or dust therein. One/of the wheel body sections, Aherein'- after termed the inner section, has axial ,1,

opening v12of larger diameter than the axleor Vshaft 2 on which the wheel isgmounted and the 'edges of said opening are turned'ut to forman internal tubular-extension l12?,

tions 4.lap overthe inner side'ofth saidjsec-v secured to solid bearing blocks or studs 6,

against the inside ofthe hollow but solid wheel rim and secured to the said rim in any bearing ring 6", the ends of which are bent approved manner. y

20 designates the wheel hub which is preferably made integral with the axle as shown in Fig. 2, but may be of two parts, as shown in Fig. 6, which shows one part 21 as integral with theaxle and the other part being inthe nature of a disk 22 which may be loosely mountedwith respect to the part 21 and held against theI same by a ball over to form retaining anges 60 when the parts are assembled. In the preferred arrangement of the hub *20, as shown in Fig.

2, the said hub has one or more annular.

grooves 25 that-form racesfor the bearing balls 7, and in the oppositesides it has annular grooves 26 for the balls 70 that' ride against the at sides of the body sections when the parts are assembled.

8 designates a hub ring that has internal grooves 80-80 thatform ball races for opposing the races 25w25 in the hub and the said ring also has a series of radial studs 81 to receive and support the lower or inner ends of coiled spring spokes 5, the said ends being secured by cross pins 83 that pass through the studs 81. The outer ends of the springs 5 are likewise secured to the rim studs 6 by the cross pins 65. By reason of the peculiar construction of the parts, as described, the hub 8 remains practically stationary, when the wheel, in striking and running over a rock or other object rises up, it being manifest that since the spoke connections with the hub are in the nature of stout coiled'springs the said spokes yield sufficiently to act as cushions for relieving the axle and running gear as well as the occupant of the vehicle, from all shocks or ars.

J In practice, the spring spokes are so made up that they have suicient elasticity to yield while the vehicle travelsrapidly over an object, and yet remain rigid to such an extent to sustain the weight of the machine and its occupant durin the ordinary or lsmoothrunning of the ve icle, without causing the lhub to sag to any marked degree' below the'axialcenter of the wheel.

By making the axial opening inthe in side body plate v1 larger than the diameter Each of wheel that has the desired resistance neces-Y sary for motor vehicles and since no direct wear comes on theresillent devices they remain practically indestructible and maintain' the conditions and rigidity desired in a wheel of the general type stated.

What I claim is 1.v A resilient wheel comprising a hollow casing having a tubular formed tire, a hub and axle rotatable within the said casing, a ring around the said hub, resilient spokes composed of coiledsprings held between the said ring and the periphery of the tubular formed tire portion of the casing, means for connecting the inner ends of the springs to the said hub engaging ring and other means for connecting theouter ends of the said springs to the tire portion of the casing.

2. In a vehicle wheel; a hollow casing including a peripheral tubular shaped tire portion and side plates, one of the plates having an axial aperture and an axle and hub projecting through the said aperture; of a ring mounted on the said hub having lugs, other lugs mounted on the inner face of the tubular portion of the casing and coil .spring spokes interposed between the ring and the tire-like rim and means for holding the springs with their inner ends l engaging the hub ring and their outer ends engaging the tubular rim portion.

3. A resilient wheel comprising a hollow casing having a tubular formed tire, said casing being composed of two half sections each .including a disk portion, the inner disk portion having an axial opening, an axle projecting through said opening, a hub on the axle and within the casing, a ring loosely rotatable on the hub, said ring havin radial lugs, other lugs secured on the lnner periphery ofthe tubular tire portion, coiled springs interposed between the ring and the tire lugs and means for securing the opposite ends ot the springs Ato the said lugs.

4. vIn a vehicle wheel, an axle having a hub,V a ring loose on said hub and having radial lugs, two Wheel disks each havingv their peripheral portions formed into a con- A cavo-convex form in cross section to provide' substantially semi-annular tiresectlons iso Legame and body plate sections, said body plate seotions being spaced apart a distance less than the diameter of said tire Sections, lugs held Within and secured to and uniting Said tire sections, spring spoke members having their ends secured to said ring and tire lugs, and means passing through said body portions to secure theniover said hub7 one only of said body portions having a sha-'ft opening.
